The Contribution of Executive Skills to Reading Comprehension

Although word recognition deficits (WRD) are a known cause of reading comprehension deficits (RCD), other contributions to RCD, including executive function (EF), have not been fully explored. We examined the contribution of EF (working memory and planning), along with attention, decoding, fluency, and vocabulary to reading comprehension in 60 children (including 16 WRD and 10 RCD), ages 9–15 years. After controlling for commonly accepted contributors to reading comprehension (i.e., attention, decoding skills, fluency, and vocabulary), EF continued to make a significant contribution to reading comprehension but not to word recognition skills. These findings highlight the need for consideration of the role of EF in RCD.     

Identification of tone duration, line length, and letter position: an experimental approach to timing and working memory deficits in schizophrenia

Patients with schizophrenia display numerous cognitive deficits, including problems in working memory, time estimation, and absolute identification of stimuli. Research in these fields has traditionally been conducted independently. We examined these cognitive processes using tasks that are structurally similar and that yield rich error data. Relative to healthy control participants (n = 20), patients with schizophrenia (n = 20) were impaired on a duration identification task and a probed-recall memory task but not on a line-length identification task. These findings do not support the notion of a global impairment in absolute identification in schizophrenia. However, the authors suggest that some aspect of temporal information processing is indeed disturbed in schizophrenia.     

Riddles in serial murder: A synthesis

This article blends the conclusions of four former law enforcement personnel who have investigated and apprehended serial killers, with pertinent principles derived primarily from the field of psychoanalysis. The four—John Douglas, Roy Hazelwood, Robert Keppel, and Robert Ressler—have written extensively about their investigations of serial killers. In their writings, they have answered many questions about the personality development of serial killers while leaving other questions only partially answered. This article expands the answers to three fundamental questions: What is the origin of the dynamics of serial killing? Why is the aggressive drive so singularly powerful and persistent in serial killers? Why is it that serial killers often reveal their identities to the police? In answering these three riddles, the contributions of four emotional pillars in the personality of killers are emphasized. The pillars include emotional hunger, anxiety and aggression, eroticism, and conscience structure. At times, these pillars merge and drive murderous behavior but the pillars lack the integration needed for healthy personality development. This synthesis offers a fuller understanding of the psychodynamics involved in serial killings.     

Negative priming without probe selection

Responses to an object may be slower or less accurate if that object shares attributes with a recently ignored object(negative priming). Some studies have found negative priming only if the probe trial required selection against a distractor stimulus. In the present experiment, subjects responded to the location of a target (O), ignoring a distractor (X) if it appeared in another location. Reaction time was slower to probe targets that appeared in the same location as the prime distractor, regardless of whether or not the probe target was accompanied by a distractor.     

Support for lateralization of the Whorf effect beyond the realm of color discrimination

Recent work has shown that Whorf effects of language on color discrimination are stronger in the right visual field than in the left. Here we show that this phenomenon is not limited to color: The perception of animal figures (cats and dogs) was more strongly affected by linguistic categories for stimuli presented to the right visual field than those presented to the left. Moreover, the magnitude of the visual field asymmetry was reduced when demands on verbal working memory were increased by a secondary task. This reduction did not occur when the secondary task imposed demands on spatial working memory. Taken together, these results demonstrate that the lateralized Whorf effect may be quite general, reflecting an interaction of linguistic and perceptual codes primarily in the left hemisphere.     

Prolegomena to a future phenomenology of morals

Moral phenomenology is (roughly) the study of those features of occurrent mental states with moral significance which are accessible through direct introspection, whether or not such states possess phenomenal character – a what-it-is-likeness. In this paper, as the title indicates, we introduce and make prefatory remarks about moral phenomenology and its significance for ethics. After providing a brief taxonomy of types of moral experience, we proceed to consider questions about the commonality within and distinctiveness of such experiences, with an eye on some of the main philosophical issues in ethics and how moral phenomenology might be brought to bear on them. In discussing such matters, we consider some of the doubts about moral phenomenology and its value to ethics that are brought up by Walter Sinnott-Armstrong and Michael Gill in their contributions to this issue.

The prediction of safe sex behaviour: The role of intentions,attitudes, norms and control beliefs

Abstract

The present study was designed to examine the utility of the theory of reasoned action (Fishbein and Azjen, 1975) in relation to people's propensity to engage in a range of different safe sex strategies, including engaging in an exclusive sexual relationship, avoiding casual sex, and asking sexual partners about their previous sexual and IV drug use history. It was proposed that the intention to engage in a particular safe sex practice would be influenced by the person's attitude towards engaging in the practice, as well as his or her perception of the extent to which others thought they should do so (subjective norm), while behavioural intentions were proposed to predict actual behaviour. The study was also designed to examine whether, after control of the effects of the components of the theory of reasoned action, the person's generalised control beliefs would explain any additional variance in either behavioural intentions or actual behaviour. One hundred and two sexually active heterosexual students participated in the study. At the first wave of data collection, subjects completed measures of intentions, attitudes, and norms appropriate to each of the different behaviours. Measures of actual behaviour were obtained at follow-tip (three months after first period of data collection). The results of the study indicated that attitudes and norms predicted intentions for avoiding casual sex and asking sexual partners about their previous sexual and IV drug use history, while intentions predicted actual behaviour for all three safe sex strategies. Although there were no significant main effects of control beliefs on intentions or behaviour, subjects with internal control beliefs were more likely than their counterparts with external control beliefs to behave in accordance with their intentions to engage in an exclusive sexual relationship and ask sexual partners about their previous sexual and IV drug use history. Additional analyses revealed that the levels and determinants of intentions and actual behaviour were, in general, similar for males and females.     

A comparison of obese and normal-weight families' sychological characteristics

Abstract

The present study assessed obese and normal-weight family members' perceptions of their nuclear family's social and environmental characteristics. Preliminary results support previous correlational and case studies that suggest obese families are dysfunctional. Results from the Family Environment Scale indicate that obese families perceive their family characteristics differently compared to normal-weight families or to a representative sample of families. Specifically, obese families perceive their homes as less cohesive, more conflictual, less interested in social and cultural activities, and less organized compared to normal-weight families. Obese parents also perceive themselves as more controlling and their families as less independent compared to nonobese parents.
